Mapping Marine Slime by Spectral Imaging
Biofilm fouling on ships (slime) is an environmentally and economically costly problem with global impacts. Alongside developing new fouling control coatings, AkzoNobel are developing complementary methods of characterizing biofilm fouling characteristics with the end goal of understanding microfouling heterogeneity and resulting drag. This is not an easy task, as many of the existing tools available to measure, identify, and characterize biofilms are, appropriately, microscale specialist techniques. In contrast ships are hundreds of meters in length. Within this context, I have developed meso and macro scale spectral imaging techniques to map fouling biomass in a quantitative and, importantly, scalable framework. This talk will cover some of the remote sensing approaches I have adopted and modified for quantifying marine fouling biofilms.
